The growing demand for bandwidth-intensive applications such as video streaming, multimedia services, and Internet of Things (IoT) deployments has intensified the need for efficient resource management that secures network operations without compromising Quality of Service (QoS). Addressing these challenges requires a comprehensive and centralized view of network resources. Software Defined Networking (SDN), as an emerging paradigm, offers centralized control and programmability, allowing administrators to dynamically manage network behavior and optimize routing. This paper introduces a QoS-aware routing scheme for SDN that considers parameters such as available bandwidth, packet delay, and packet loss to determine the most efficient routing paths. Optimal paths are selected based on predefined threshold criteria to meet users’ QoS expectations. Furthermore, we explore the integration of SDN with the Service-Oriented Architecture (SOA) model, emphasizing a user-centric approach to traffic engineering and Quality of Experience (QoE) enhancement. QoS guarantees remain essential for optimizing performance metrics and ensuring reliability, especially under constrained network conditions. Controllers dynamically identify optimal routes to meet clients’ core QoS requirements, highlighting QoS-aware delivery as a cornerstone for next-generation network design.
